I have built a cool little prototype ML algo that can estimate population density in 20m resolution from S2 imagery. Here are 5 examples. Row1: Sentinel-2. (input data) Row2: population density from eurostat. (input data) Row3: ML model population density. (output data)

Why do these 2 numpy lines not give the same result? Aaargh! data[range(1,3),range(1,3)].shape -> (2,) data[1:3,1:3].shape -> (2,2) I don't want the diagonal!

Bedrock reached at the Ice coring on Müller ice cap (Axel Heiberg Island). I bet that we would reach at 611m --- pretty close to the final 613m. (Bo guessed 612m so i didn't win).

Greenland accumulation in terms of cucumbers. * Greenland acc = ~600Gt/yr. * global pop = ~9bn. So ~7.5 kg/person/hour * cucumber water content = ~166g So ~45 cucumbers/person/hour Unfortunately global cucumber production is only 95 Mt/yr = 1.2 cucumber/person/week 🥲

Norge vil lokke forskere til landet: 'Det handler især om situationen i USA'. I Norge har Forskningsrådet, der prioriterer og deler penge ud på vegne af staten, afsat 100 millioner norske kroner (cirka 63 millioner kroner) til at lokke udenlandske forskere til landet.

I need a new circular saw and would like the batteries to be compatible with my other DeWalt tools. But i am wondering if i should jump ship to some non-US brand. Also - they apparently have extra high exposure to the tariff situation.

Moomin=Kant? Tove Jansson made the first drawing of a moomin troll in an outhouse after an argument with her brother where one of them was quoting Immanuel Kant. I heard two different versions of that story. In one of them the Moomin troll was intended as a caricature of Kant.

I'm considering if my continuum mechanics course should cover some intro plasma physics too in the future. Any good books that span that space? Some keywords: (elastic solids, viscous fluids, to plasma physics).

I am looking at different Lab/Lch colorspaces (OKLab/SR2Lab/...) - One issue they share is that the RGB color you get for very dark L-values becomes negative. Seems non-sensible to me.

Anybody has access to recent very high resolution satellite imagery of Greenland. We want to know if a Ø22cm pipe is still sticking out of the ice at this location: 75.09714423N, 42.31992755W (5m uncertainty) Please help - it could save a lot of fuel (It is the NGRIP borehole casing)

Colonial mining profits... Denmark has made huge profits from a cryolite mine in Greenland. A new explosive documentary has sparked debate in DK. I think the criticism of the documentary is a bit unfair - the caveats regarding the 400bn are clearly highlighted IMHO.

After #Trump used a Sharpie to alter the projected path of #HurricaneDorian on a map to show #AL in its path, #NeilJacobs helped draft a #NOAA statement backing Trump’s projection. An internal NOAA report determined Jacobs violated the agency’s scientific integrity policy by issuing the statement.
